EMC GUIDELINES FOR MICROCONTROLLER-BASED APPLICATIONS

4 CONCLUSION

The purpose of this application note is to convince designers of microcontroller applications to

take EMC performances into consideration at the very beginning of the project.

Most of the EMC improvements presented in this document are already known, but they must

be applied. There is no single action to meet EMC performance requirements, as each tech-

nique yields a small improvement. Only a comprehensive application of the techniques men-

tioned can lead to optimum EMC performances. STMicroelectronics, which has acquired ex-

tensive EMC expertise for their microcontrollers, makes their expertise available to their cus-

tomers.
